The rolls B and C Aare geared together, as indicated by the dot-ted lines marked t. The table D and the rolls B should be furnished with cogs which gear into each other, as indicated bythe dotted lines marked 01:. y

R represents the bar of heated iron for forming the spikes. The size and manner of constructing the several parts `'described I leavc-to the skill and judgmentof the mechanic, Who will readily see andfnderstand the construction and operation ot' the various parts and the relation they bear to each other by reference to the accompanying drawings.
